Auction Fever and Sticky Wild Bids

Key takeaways

Theme & first impressions

Sold It Bonus Buy slot has a clear antique auction-house theme, with the Wild multiplier system doing more of the heavy lifting than the setting itself. You get red curtains, a 5-reel stage, an auctioneer with a gavel, a podium on the left, and a covered display case on the right.

The golden toad Scatter gives the scene its odd little hook. You’ll notice it sits apart from the usual antique items, which helps it stand out during fast spins. The demo uses DEMO play money, so I report results as bet multiples rather than treating the balance as cash. SatoshiHero has the game available in demo and real play, and my test started from a 5,000.00 DEMO balance at the default 10.00 DEMO bet.

The auction-house idea feels more distinctive than another treasure or fruit setup. Still, the Wild multiplier ladder gives this Evoplay game its real personality. If you like character-led caper slots, Bandit Bust Bonus Buy leans harder into that style, while this one keeps the spotlight on bids and Sticky Wilds. You see the theme first, but the mechanics decide whether the session has teeth.

How Sold It Bonus Buy slot works

Fixed line wins

Tested pay example

I checked the paytable unit on a real line hit. Four blue coins paid 12.00 DEMO at a 10.00 DEMO bet, which equals 1.2x. That result confirmed two useful things for me: the game uses total-bet multiples, and the low coin symbols follow the left-to-right line-pay setup.

That example matters because small wins can look larger in balance terms than they really are. A 12.00 DEMO return felt neat on screen, but it only covered a little more than one spin. You’ll get more value from reading wins as multiples than staring at the raw demo balance. That habit helps a lot once the bonus-buy menu appears.

Symbols and pay values

Premium symbols

The green cat is the top regular symbol. It pays 0.7x for 2, 1.5x for 3, 4.5x for 4, and 12x for 5. That 2-symbol pay gives it a small edge over the other premiums, especially when a Wild Bidder helps form the line.

The gramophone pays 1x for 3, 3x for 4, and 8x for 5. The blue chest and vase each pay 0.7x for 3, 2x for 4, and 5x for 5. You’ll notice the premium gap quickly: the cat can deliver a much better full-line hit, while the other antiques need Wild multipliers to feel lively. That isn’t a flaw, but it does make the game more feature-led than symbol-led.

Coin symbols

The gold, green, orange, and blue coins are the low symbols. Each coin pays 0.5x for 3, 1.2x for 4, and 2.5x for 5. The word coin matters here because these are actual symbol types, not a currency unit.

Those values explain why my four-blue-coin hit paid exactly 1.2x. You might see plenty of these smaller line wins during a session, but they rarely shift the result by themselves. When a Wild Bidder connects with coin symbols, the multiplier can make the same low-symbol hit feel more useful. Without that help, the paytable keeps you waiting for a better setup.

Wild Bidders and the multiplier ladder

Wild reels

Wild Bidders appear only on reels 1, 2, 4 and 5. They substitute for every symbol except the golden toad Scatter, and they have no pay of their own. Any win involving a Wild Bidder gets multiplied by that Wild tag.

This design creates a clear split between dead Wilds and useful Wilds. A Wild on the wrong line can look exciting, then do nothing. A Wild that connects with a cat or gramophone line can change the whole spin. I like that tension, because you can read the outcome quickly without needing a long feature animation.

Fast Fact: Wild multipliers add together on the same payline, so two Wild Bidders can matter more than one isolated Wild.

Added multipliers

Antique Free Spins

Trigger rules

The golden toad Scatter lands on reel 3 only. A Scatter plus at least one Wild Bidder starts 8 Antique Free Spins. The triggering Wild Bidders take a multiplier from x1, then become Sticky and stay for all 8 free spins.

You can see why the trigger feels picky in practice. The Scatter must appear on its single reel, and a Wild Bidder must join it from the eligible reels. I waited until spin 98 for my only bonus. That late arrival shaped the whole test, because the base game had already dug a deep hole.

Trivia: The golden toad Scatter has two theme-linked jobs: it starts the auction-house free spins with a Wild Bidder, and inside the round it raises every Sticky Wild multiplier by 1.

Sticky Wilds

Every new Wild Bidder increases its own multiplier by 1 from the highest Wild on screen. New Wild Bidders also become Sticky, so the reels can build during the 8 spins. A Scatter on reel 3 during free spins adds 1 to every Wild multiplier on the reels.

My tested round landed on spin 98 and paid 11.6x the bet. The Wild multiplier reached x2, and I didn’t see a retrigger. That round pulled the session back, but it didn’t create a full comeback. You might find the build-up easy to follow, though the result can still land small if premium symbols don’t connect.

The feature has good visual logic. Sticky Wilds stay where you can track them, and the multiplier counter gives you a clean target. My issue is the same one you’ll feel in many high volatility games: one late bonus can arrive, play cleanly, and still leave you behind. That makes the feature exciting, not forgiving.

Bonus Buy options

Buy prices

The Bonus Buy button sits on the left and starts the 8 free spins straight away. The four options are:

• 33x total bet: Sticky Wild on reel 1
• 75x total bet: Sticky Wilds on reels 2 and 4
• 128x total bet: Sticky Wilds on reels 2, 4 and 5
• 300x total bet: Sticky Wilds on reels 1, 2, 4 and 5

I didn’t use the buy feature because this test covered base-game spins only. That choice matters because a bought round changes the cost profile. You skip the waiting, but you also pay many spins upfront. You should treat each buy as a separate risk decision, not as a shortcut to guaranteed value.

Tip: If you test the buy feature, think in multiples of your bet, not coin balance. A 300x buy commits 300 normal spins of stake at once.

Risk trade-off

How the 100-spin test played

Cold opening

I played 100 spins on a fresh 5,000.00 DEMO balance at the default 10.00 DEMO bet. That made the stake 1x per spin. I finished at 4,673.00 DEMO, which left the test 32.7x down.

The start was cold and a little blunt. I was 16x down after 17 spins with only one 1x return. My biggest base-game win arrived on spin 18 and paid 12.3x, which briefly stopped the slide. By spin 90, though, I was 38.4x down again. You can see the pattern there: the game gave me a useful hit, then slowly took control back.

Alert: High volatility showed up clearly in the test. One feature in 100 spins wasn’t enough to turn the session positive, so don’t size bets as if the bonus can rescue every dry run.

Late feature hit

RTP, volatility & simulator

Simulator projection

The SatoshiHero Slot Simulator used 96.16% RTP, high volatility, and a 3,536x maximum win. Every figure in the model is a multiple of the bet. The median 1000-spin session ends 67.2x down, which gives you a sober baseline before you press spin.

The 5th to 95th percentile band runs from 319.8x down to 364.1x up. About 18% of spins pay something, and a feature round lands roughly once in 45 spins. A 100x or bigger win appears about once in 1,754 spins.

Those numbers explain why the game can feel slow even when its RTP looks solid. An 18% paid-spin rate leaves plenty of dead space. A feature every 45 spins sounds manageable, but one weak round can still leave you waiting for the next real chance. The model can’t predict your next session or the real random number generator. It only shows the spread you should respect.

Fast Fact: The simulator’s median 1000-spin result sits 67.2x down, even with the official 96.16% RTP in the model.

Our 100-spin session

My 100-spin session finished 32.7x down. I saw one feature, logged a 12.3x best base-game win, and got 11.6x from Antique Free Spins. No retrigger appeared, and the late feature felt more like damage control than a turnaround.

That result sat below break-even but still fit the simulator’s swing profile. The test didn’t hit a 100x result, which the model places far outside a short session. You’ll notice how quickly the gap appears between a fair theoretical setup and a cold run. That’s why I wouldn’t judge this game from ten spins, or from one bought bonus.

The theoretical RTP is the operator’s published figure, while one live or demo session doesn’t change that number. Simulator figures are illustrative spread estimates, not predictions, and any bonus-buy returns can differ by design when the operator supplies separate figures.

Closing Thoughts

Sold It Bonus Buy stands out through its Sticky Wild Bidders, simple line structure, and auction-house bonus chase. Its main drawback is the gap between a readable feature and a session that can still stay cold for long stretches.

My Verdict

Patient high-volatility players should get the most from this game, especially if they enjoy tracking Wild positions and multiplier tags. Expect quiet base-game spells, occasional neat line hits, and bonus rounds that can save damage without always flipping the result.

I like how clearly the Wild ladder works, because I never felt lost during the free spins. I don’t like how modest my only feature felt after waiting until spin 98. The 11.6x bonus helped, but it didn’t erase the earlier dry spell.
